@BBDS yes it was, but 2001 came out in 1999. Dre was going to name it Chronic 2000 (cus everyone was adding 2000 to things in 1999) but right before the album release Suge Knight put out a shitty compilation album under the name “The Chronic 2000”. So Dre dropped 2001 to literally one-up them. Don’t worry, thinking 2001 came out in 2001 is a common mistake, hell, Game made it on an album where Dre was the executive producer
